REVERSIBLE NUCLEAR GENETIC SYSTEM FOR MALE STERILIZATION OF TRANSGENIC PLANTS.

摘要

THE DEVELOPMENT OF THE PLANTS CAN BE ALTERED BY TRANSFORMING A PLANT WITH A GENETIC HANDLING THAT INCLUDES REGULATING ELEMENTS AND SEQUENCES OF CAPABLE DNA TO ACT INHIBITING THE POLLEN FORMATION OR ITS FUNCTION AND, THEREFORE, PRODUCING A MALE REVERSE PLANT. IN PARTICULAR, THE PRESENT INVENTION REFERS TO THE USE OF DOMINANT NEGATIVE GENES AND OF A SPECIFIC PROMOTER OF THE PREVIOUS. THE STERILITY OF THE MALE PLANT CAN BE RECOVERED BY INCLUDING A SECOND GEN FRAGMENT TO THE PLANT THAT REPRESSES THE DOMINANT NEGATIVE GEN. THE INVENTION ALSO REFERS TO NEW DNA SEQUENCES WITH THE ABILITY TO SERVE AS SPECIFIC PROMOTERS OF ANTERAS IN PLANTS.
